INSTALLATION
Gas connection
Before connecting the appliance check that the
data on the rating plate affi xed to the cooker,
correspond to those of the gas mains.
A label on the back of this handbook and at the
back of the cooker gives the appliance adjustment
conditions, that is, the type of gas and operating
pressure.
Once the cooker is installed, check there are no
leaks using a soapy solution (never a fl ame).
The appliance’s gas inlet fi tting is a threaded 1/2” male
cylindrical type, in compliance with the UNI-ISO 228-
1 standards. If gas is distributed through ducts the
appliance must be connected to the gas mains with:
• a rigid steel pipe, in accordance with standards,
whose joints must be made using threaded fi ttings
in accordance with the UNI-ISO 7/1 standard. The
use of hemp with suitable adhesives or Tefl on tape
as a sealant is allowed.
• copper pipe, in accordance with the standard,
whose joints must be made using sealed fi ttings in
accordance with the standard.
• a fl exible stainless steel, seamless pipe in accordance
with the standard, with a maximum 2 metre
extension and seals in accordance with the standard.
• a fl exible rubber hose in accordance with the
standard, with an 8 mm diameter for LPG and 13
mm for natural gas or town gas, maximum 1500
mm in length, fi rmly secured to the hose fi tting
with a safety clamp as per the standard.
If the gas is supplied directly from a gas cylinder, the
appliance, fed by a pressure regulator in accordance with
the standard, must be connected:
• with a copper pipe in accordance with the
standard, whose joints must be made using sealed
fi ttings in accordance with the standard.
• with a fl exible stainless steel, seamless pipe in
accordance with the standard, with a maximum
2 metre extension and seals in accordance with
the standard. We recommend applying the special
adapter to the fl exible pipe, easily found on the
market, to facilitate connection to the pressure
regulator’s hose fi tting on the cylinder.
• with a fl exible rubber hose in accordance with the
standard, with an 8 mm diameter, minimum
400 mm in length, maximum 1500 mm in length,
fi rmly secured to the hose fi tting with a safety
clamp as per the standard.
CAUTION
If the appliance is going to be recessed (class 2
subclass 1), connect it to the gas supply source
using only fl exible stainless steel, seamless pipes in
accordance with the standard.
CAUTION
If the appliance is going to be installed free-standing
(class 1) and if you use the fl exible rubber hose, it is
necessary to follow the instructions and fi gures given
below (fi g. 20)
